First, the operator should strictly follow the instructions for use and maintenance. Drinks, lack of sleep, illness, pregnant women, under the age of 18, and no qualification certificate are not allowed. After the work is completed, stop the engine, turn off the power of the remote controller, place the remote controller in the tool box, and take out the key. When the plant protection machine emerges from an emergency situation, the plant protection machine should be removed from the crowd as quickly as possible and landed or forced to land as soon as possible.
Second, the flight controller should develop good habits. Before each start of the plant protection machine, routine inspections must be performed. From top to bottom, from front to rear, from outside to inside, the engine can be started after checking.
Third, it is necessary to develop good habits after each flight to maintain and clean the entire aircraft. Airframes, rotors, landing gear, spray systems, etc. can be cleaned with compressed air, soft cloths, and diluted detergents. At the same time, check whether the screws of the main components of the helicopter are firm, whether the swinging amplitude of the moving parts is too large, whether the push rod is firm, and whether the fuselage has obvious cracks.
Fourth, flying is forbidden on rainy days. Winds with a wind force greater than 4 are temporarily suspended and operations with winds greater than 6 are prohibited.
Fifth, there are no residential buildings within 10 meters of the perimeter of the field. There are no barriers such as shelterbelts, high-voltage towers, and electric poles within 10 meters of the perimeter of the field. There are no obstructions affecting flight safety or obstacles affecting the sight of the flight in the middle of the field. There is a suitable landing point for the aircraft in the perimeter of the work field or in the middle of the field. The height of the crop should be lower than that of the operator, and the operator can observe the attitude of the aircraft. Work plots should have suitable roads for the operators to walk.
Single Packed Mottled Waxy Corn
Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.
Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...
Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.
Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
